Linear guides are essential in any industrial environment and can help move equipment and objects on the production line. Marcus Schneck, CEO of norelem, explained the factors to be considered when specifying linear guides.
When it comes to manufacturing, linearity is of utmost importance. In demanding applications such as factory automation, the system must have absolute linearity, because the production line relies on machines that can reliably move along a predetermined axis over and over again.
In order to achieve the quality of linear transmission, design engineers use linear guides. In principle, this technology can help people all over the world to reliably open their clothes drawers day after day. However, the risks in the factory environment are much higher. Linear guides need to be sturdy and frictionless, maintain their performance in thousands or even millions of repetitive motions, and must withstand force without deformation.
Which linear guide is right for you?
There are two main types of linear guide systems, and each type has its own specific characteristics.
The sliding guide is a linear guide in which the individual linear guide elements are not separated by rolling elements. The linear sliding guide system includes a dovetail slider from norelem, which prevents the guide element from lifting during the rotational movement, which is ideal for absorbing and damping shock and vibration.
Telescopic slides are another option-norelem's product line can provide effective movement for payloads ranging from 10 kg to 450 kg and help reduce friction, noise and maintenance requirements.
The standard material of the slide rail is steel, but there are also stainless steel or aluminum.
In contrast, roller guides are based on a rotating mechanism, whereby a roller or ball bearing rotates between two moving elements.
Rolling element retainers (such as roller chains) control the rolling elements and ensure that the guide rail runs as quietly as possible. Roller guides include profile guides and linear ball bearings.
norelem's roller guide system includes guide rails of various lengths that can operate under static loads up to 5,500 N and dynamic loads up to 12,280 N.
Another type of roller guide involves roller guides with endless rolling elements. The rolling elements recirculate within the linear block and move together with the block instead of moving separately, similar to the track of a tank.
